NO REGEX OR ANYTHING COMPLICATED PLEASE.. USE BASIC APPROACH
Create a program in Python that reads data from Breakfast Menu (https://www.w3schools.com/xml/simple.xml) and builds parallel arrays for the menu items, with each array containing the menu item name, description, calories, and price, respectively. After reading the data and building the arrays, display the menu items similar to the following:
name - description - calories - price
At the bottom, display the total number of items on the menu, the average number of calories per item, and the average price per item similar to:
0 items - 0 average calories - $0.00 average price
You may either read the page using Internet processing methods, or you may download and save the page and then read the data from the saved file. You must process the data using string functions (no XML libraries).
must use separate subroutines/functions/methods to implement each type of processing, and include error handling for missing or invalid data.
THE BREAKFAST MENU IS BELOW:
WHAT I HAVE SO FAR BELOW:
def read_data():
with open("simple.xml", "r") as file:
string = file.read()
def extract_data(tag, string):
data = []
start_tag = f"<{tag}>"
end_tag = f"</{tag}>"
while start_tag in string:
start_index = string.find(start_tag) + len(start_tag)
end_index = string.find(end_tag)
value = string[start_index:end_index]
data.append(value)
string = string[end_index + len(end_tag):]
return data
def get_data():
names = extract_data("name", string)
prices = extract_data("price", string)
descriptions = extract_data("description", string)
calories = extract_data("calories", string)
def display_menu(names, descriptions, calories, prices):
for i in range(len(names)):
print(f"{names[i]} - {descriptions[i]} - {calories[i]} - {prices[i]}")
def display_stats(total_items, average_calories, average_price):
total_items = len(names)
average_calories = sum(map(int, calories)) / total_items
average_price = sum([float(price[1:]) for price in prices]) / total_items
print(f"\n{total_items} items - {average_calories:.1f} average calories - ${average_price:.2f} average price")
def main():
read_data()
extract_data(tag, string)
get_data()
display_stats(total_items, average_calories, average_price)
display_menu(names, descriptions, calories, prices)
main()

Knight's Tour is a fascinating problem that is done on an electronic chessboard with a knight. Starting at any location on the chessboard, a knight proceeds to move on the board in such a manner that all positions on the chessboard are visited, once and once only. The knight may only move according to the rules of chess playing. The matrixes below show a sequence of knight moves that starts from the top-left corner. In most cases, the knight is locked in place and can go no farther. Note: there are only 3 legal knight moves from the 44 locations and they have already been visited. 01 60 39 34 31 18 09 6438 35 32 61 10 63 30 1759 02 37 40 33 28 19 0836 49 42 27 62 11 16 2943 58 03 50 41 24 07 2048 51 46 55 26 21 12 1557 44 53 04 23 14 25 0652 47 56 45 54 05 22 13 01 22 39 20 03 18 09 1600 37 02 23 08 15 04 1335 40 21 38 19 12 17 1000 00 36 41 24 07 14 0500 34 00 32 00 28 11 2600 00 00 00 42 25 06 2900…arrow_forward

The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 – 9 exactly The sum of each row, each column and each diagonal all add up to the same number. This is shown below: Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Do not use two-dimensional array. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not.
